BACKGROUND Technical Field

The present disclosure relates to a vehicle seat. More particularly, the present disclosure relates to a temperature-control system for the vehicle seat.

Description of Related Art

A vehicle, such as a sedan, a Sports Utility Vehicle (SUV), a Multi Utility Vehicle (MUV), a van, a bus, a truck, and the like, includes one or more seats to accommodate a driver and passengers. During warm and/or humid weather conditions, vehicle seats will become warm and may cause occupants to perspire, especially in areas of seat contact, creating an uncomfortable environment. Conversely, during cold weather conditions, vehicle seats can be cold, similarly creating an uncomfortable environment.

Conventional vehicle seats do not solve the aforementioned problems. Attempts to provide air ventilation through the seat foam are typically insufficient to remove excess heat and provide a comfortable environment for the occupant. Further, conventional heating systems are bulky, occupy space in the seat which typically requires the seat to be thicker, and are inefficient in heating the seat as the heat typically must travel through multiple layers and heats regions of the seat that the occupant does not contact. Hence, there is a need for an improved temperature-control system for vehicle seats.

The seat 100 further includes a temperature-control system 110. FIG. 1B is a partial cross-sectional view of the temperature-control system 110. The temperature-control system 110 may be referred to as the “system 110.” In the illustrated embodiment, the system 110 will be described with reference to the seating portion 102. The system 110 may be, additionally or optionally, employed within the backrest portion 104 and/or the headrest portion 108. The system 110 includes a base layer 112. The base layer 112 extends at least partially along a width “W” and a length “L” of the seating portion 102. The base layer 112 may be made from a polymer foam, a polymer wire mesh, or another suitable material. In some embodiments, the base layer 112 is made using a cushion foam, a nylon wire mesh, or another non-metallic material.

The system 110 includes an intermediate layer 114. The intermediate layer 114 is disposed adjacent to the base layer 112. The intermediate layer 114 extends at least partially along the width “W” and the length “L” of the seating portion 102. The intermediate layer 114 includes a substantially porous configuration, for example a continuous network of pores. The intermediate layer 114 allows fluid to flow through it. In the illustrated embodiment, the fluid flow is substantially perpendicular to the intermediate layer 114, as shown by arrows 115.

In an embodiment, the cover layer 116 is a leather or synthetic leather with a foam.

The system 110 includes heating elements 118 disposed between the intermediate layer 114 and the cover layer 116. In FIG. 1B, two heating elements 118 are shown. In other embodiments, there is one heating element 118. In other embodiments, there are multiple heating elements 118. Each heating element 118 is spaced apart from another. Each heating element 118 provides heat to the seating portion 102 to increase its temperature. Each heating element 118 may be an electrically powered heating element, a copper-based heating element, a heat pipe, or another heating element.

As shown in the embodiment illustrated in FIG. 2A, the system 110 includes the base layer 112, the intermediate layer 114, the cover layer 116, and the heating elements 118. Fluid flow is substantially parallel to the intermediate layer 114, as shown by arrows 208. In some embodiments, a distribution layer 202 is associated with each heating element 118. The distribution layer 202 may provide substantially even distribution of heat generated by each of the heating elements 118. The distribution layer 202 may be made of a metal, a conductive polymer, or another thermally-conductive material that distributes heat.

Further, a gap 203 may separate heating elements 118 and may allow air to flow, improving heat distribution. Each heating element 118 may also include an insulating layer 204 to thermally or electrically insulate the heating element 118 from other areas within the layer or other components. In embodiments, the insulating layer 204 allows for the distribution of heat towards the cover layer 116 and limits the spread of heat to other portions of the system 110, such as the intermediate layer 114 and/or the base layer 112. The insulating layer 204 may be a polymer, rubber, or another insulating material. The heating elements 118, the distribution layer 202, and/or the insulation layer 204 may be disposed non-continuously across the width “W” and the length “L” of the seating portion 102.

As shown in the embodiment of FIG. 2C, each of the heating elements 118, the distribution layer 202, and/or the insulation layer 204 are disposed between the base layer 112 and the intermediate layer 114. In some embodiments, such as the one shown in FIG. 2D, the heating element 118 includes a single heating element 118. In other embodiments, there are multiple heating elements 118. The heating elements 118 may be disposed between the base layer 112 and the intermediate layer 114. In the illustrated embodiments of FIGS. 2C and 2D, the flow of the fluid is substantially parallel to the intermediate layer 114, as shown by arrows 206. In other embodiments, the flow of the fluid may be in any direction, such as perpendicular to the intermediate layer 114, based on application requirements.

As shown in FIG. 1B, the system 110 includes one or more fluid pumps 120. Each fluid pump 120 provides fluid that flows through the intermediate layer 114. In embodiments, the fluid is water. In other embodiments, the fluid is an aqueous-based coolant. In such a situation, the fluid pump 120 is a liquid pump. In embodiments, the fluid is air. In such a situation, the fluid pump 120 is an air pump. In one embodiment, the fluid pump 120 provides flow of a fluid that has a lower temperature than the seating portion 102. The flow of the fluid cools the seating portion 102 by reducing its overall temperature or the temperature in specific regions where the occupant is seated.

In another embodiment, when the heating elements 118 are active, the flow of the fluid may distribute heat generated by the heating element 118 across the seating portion 102. In another embodiment, the fluid pump 120 provides the flow of the fluid that has a relatively higher temperature with respect to the seating portion 102. In such a situation, the flow of the fluid heats the seating portion 102 by increasing its overall temperature, or the temperature in specific regions where the occupant is seated. In such an embodiment, the heating element 118 may be, optionally, omitted.

The system 110 also includes a support portion 122 disposed adjacent to the seating portion 102 and may be next to the fluid pump 120. The support portion 122 is also disposed adjacent to the base layer 112. The support portion 122 may be made of a metal, a polymer, or another suitable material. In embodiments, the support portion 122 is made from an aluminum sheet or a plastic sheet. Further, the base layer 112 may be partially or fully embedded within the support portion 122.

Also, each conduit 502 is disposed in the seating portion 102 and extends along the length “L” of the seating portion 102. In some embodiments, when the conduits 502 are disposed within the backrest portion 104, the fluid pumps 120 may be disposed at the bottom of the backrest portion 104, such that the flow of the fluid exits at the top of the backrest portion 104. Also, each conduit 502 may extend parallel to the backrest portion 104. Each conduit 502 provides the flow of the fluid through an extended distance within the seating portion 102 and/or the backrest portion 104. In some embodiments, an aluminum wire mesh is thermally connected to the conduits 502 to improve heat transfer.

Each conduit 502 allows fluid to flow through it, as shown by arrows 506. In embodiments, each conduit 502 includes a pressure-based valve (not shown), such that the pressure-based valve actuates the flow of the fluid based on the pressure applied by the occupant on the seating portion 102. As such, the seating portion 102 may be heated or cooled based on transfer of heat between the fluid and the intermediate layer 114 via each conduit 502. In some embodiments, the conduits 502 includes interconnecting conduits 504 disposed between each conduit 502. The interconnecting conduits 504 provide rigidity to the conduits 502. In embodiments, the interconnecting conduits 504 provide cross flow of fluid between the conduits 502. The conduits 502 and interconnecting conduits 504 may be made of metal, polymer, or another suitable material. In embodiments, one or more conduits 502 or the interconnecting conduit 504 is a heat pipe.

FIG. 5B illustrates a partial cross-sectional view of the system 110 of FIG. 5A. Each conduit 502 is disposed next to the base layer 112. In an embodiment, the conduits 502 are embedded in the base layer 112. The heating element 118 is disposed between the cover layer 116 and the conduits 502 and/or the base layer 112. As illustrated, the intermediate layer 114 is omitted. In other embodiments, the conduits 502 are disposed next to the intermediate layer 114, with the intermediate layer 114 disposed between the cover layer 116 and the base layer 112. The conduits 502 may be disposed next to the base layer 112 or the intermediate layer 114, and the heating element 118 may be disposed between the cover layer 116 and the intermediate layer 114, or the intermediate layer 114 and the base layer 112, based on application requirements.

FIGS. 6A and 6B illustrate top view and partial cross-sectional view, respectively, of another configuration of the system 110. The system 110 includes the conduits 502 and the heating elements 118. As shown, there are four heating elements 118. In embodiments, the heating element 118 includes a single or multiple heating elements 118 based on application requirements. Each heating element 118 is disposed substantially parallel to and spaced apart from one another. The heating elements 118 may also be spaced apart from the conduits 502. Each heating element 118 may be disposed adjacent to each conduit 502. In embodiments, the heating elements 118 are integrally formed with each conduit 502. In other embodiments, the heating elements 118 are woven directly into the conduits 502. For example, as illustrated, each heating element 118 is disposed in a gap 602 provided between the conduits 502.

FIG. 7 illustrates a schematic representation of the system 110. The system 110 includes the fluid pump 120. In embodiments, the fluid pump 120 is disposed next to the seating portion 102 of the seat 100. In embodiments, the fluid pump 120 is located away from the seat 100. The system 110 also includes the heating element 118 associated with the seating portion 102 of the seat 100. Each of the fluid pump 120 and the heating element 118 is communicably coupled to a controller 702.

In embodiments, the controller 702 is a dedicated control unit configured to perform functions related to the system 110. In other embodiments, the controller 702 may be an Electronic Control Unit (ECU) associated with the vehicle, or another control unit, configured to perform functions related to the system 110.

Additionally, the system 110 includes a switch 704 communicably coupled to the controller 702. The switch 704 provides an input to the controller 702 in order to control the fluid pump 120 and the heating element 118. In embodiments, the switch 704 is a manual switch adapted to receive the occupant input indicative of actuating the fluid pump 120 and/or the heating element 118. In embodiments, the switch 704 is a temperature-based switch adapted to provide the input indicative of actuating the fluid pump 120 and/or the heating element 118 based on exceeding or dropping of the temperature of the seat 100 beyond a threshold.

In other embodiments, the switch 704 is a pressure-based switch adapted to provide the input indicative of actuating the fluid pump 120 and/or the heating element 118 based on the pressure applied on the seating portion 102 of the seat 100. In such a situation, the switch 704 may be associated with a pressure-based valve element (not shown). The pressure-based valve element may be provided in the seating portion 104 and may be actuated based on the pressure applied by the occupant. The pressure-based valve element may, in turn, actuate the switch 704 to selectively allow the flow of the fluid from the fluid pump 120 or actuate the heating element 118 based on the pressure applied on the seating portion 102 by the occupant.

The system 110 provides a simple, efficient, and cost-effective method of controlling the temperature of the seat 100. The system 110 may be employed with any portion of the seat 100, such as the seating portion 102, the backrest portion 104, and/or the headrest portion 108. The system 110 provides substantially uniform cooling of the seat 100 by employing the intermediate layer 114 and/or the conduit 402, and improved distribution of the cooling/heating.
